Renal Mechanism of Trimethoprim-induced Hyperkalemia. From the Department of Veterans Affairs Medical Center, West Haven, Connecticut; Yale University School of Medicine, New Haven, Connecticut.
The clinical manifestations of hyperkalemia will be reviewed here. The causes, diagnosis, treatment, and prevention of hyperkalemia are discussed separately. The most serious manifestations of hyperkalemia are muscle weakness or paralysis, cardiac conduction abnormalities, and cardiac arrhythmias. These manifestations usually occur when the serum potassium concentration is â¥7.0 meq/L with chronic hyperkalemia or possibly at lower levels with an acute rise in serum potassium.
